Here's the scoop:

Land o' Lakes packaged, sliced provo: $7.59 / lb.

At the deli counter,
a. house brand: $6.99 / lb.
b. Deitz and Watson: $7.99 / lb.

Guess it all depends on how much time you have and how frugal your'e feeling. No 'sale' prices were in effect that day on any of these three.

HTH

Next, I may buy all three and do a blind taste test.
